Abstract: PURPOSE:To decrease a leakage of steam by cooling the steam descending and flowing in a cooling tube with a cold air flow in a cold air tube. CONSTITUTION:Steam ejected into a steam chamber 20 through a hole opened in an inner cover 19 is guided by a leading-in tube 41 and fed out to a descending spiral cooling tube 43 of a main body 1 side through a closed and connected connector 42. On the other hand, a cold air tube 44 arranged along the cooling tube 43 is affected by a rice cooking temperature in the main body 1 and reaches a temperature a little higher than an outside temperature. Therefore, a convection action is generated inside the cold air tube 44 and from an opening of the lower end part, cold air in the vicinity of a water receiver 46 is sucked in, and an air flow for exhausting warm air to the vicinity of a hinge mechanism 23 from an opening of the upper end part is generated. As a result, by a cold air flow inside the cold air tube 44, steam descending and flowing spirally in the cooling tube 43 is cooled. The cooled steam is condensed, becomes waterdrops, flows down in the cooling tube 43, drops down into the water receiver 46 from the tube end of the lower part, and the steam is prevented from being leaked to the periphery.
